Whole Numbers

🔹 What Are Whole Numbers?

Whole numbers are numbers without fractions or decimals.
They start from zero and go on forever:

Zero, one, two, three, four, five… and so on.

These are the numbers we use to count, add, and multiply in everyday life.

🧠 Clue to Remember

Whole numbers are complete — no parts, no pieces, no decimals.

If a number has:

• A decimal (like 4.5) → it is not a whole number.
  
  

• A fraction (like 3 over 4) → it is not a whole number.
  
  

Only numbers like 0, 1, 2, 3, 100, 1,000 are whole numbers.

💡 Why Whole Numbers Matter

• They help us count objects (like people, books, apples)
  
  

• We use them in math operations: addition, subtraction, multiplication, division
  
  

• They are the foundation of all number systems in school math
  
  

🔍 Real-Life Clue

If someone says, “I have 3 whole apples,”
they mean full apples — not half or part of one.
That’s a whole number: 3.

✏️ Important Notes

• Zero is the smallest whole number
  
  

• Whole numbers do not include negative numbers
  
  

• Whole numbers are always exact and complete
